The aim of this project is to create a free (open source, OS independent) remake of the classic SSI game Imperialism. While the spirit and many concepts of the original should be preserved, it should not become a pure copy but advance the concept in a sense that modern elements of strategic games are included, e.g. of the Civilization series. The game is written in Java using Swing for the user interface. The philosophy is to keep it as simple as possible, use standard/well tested libraries wherever possible and to demand clean, understandable code.

OpenXcom is a new engine for the old game UFO: Enemy Unknown (X-Com: UFO Defense in the USA),
a popular strategy videogame made by Mythos/Microprose in which you take control of the X-Com
organization to fight off the alien menace invading Earth.
